Yes, he has. Poorly. And his career, and the Twins starting rotation, shipwrecked on the decision.

Redmond's making room for an injured pitcher who's returning to the rotation, plus there's this: Slowey, who got off to a very strong start to the season (he had a 1.81 ERA after a May 5 start), has been pretty bad since (7.08 ERA in his last seven outings). The best of those outings was a seven-inning shutout emergency relief job in a 19-inning win June 8, which might be part of why Redmond thinks he's a good fit for long relief.

My guess, however — and Redmond hints at this in the above link — is that Slowey-to-the-pen is temporary. The Marlins may have an excess of starting candidates at the moment, but that's likely to change. Pretty good chance at least one starter gets hurt. Jose Fernandez, their best starter, is just 20; the Marlins may want to shut him down early. We're in the middle of June, and the July trading rumors are revving up; Ricky Nolasco is a pretty likely trade candidate.
